摘要 :
An amplifier system having first and second interleaved half bridge stages and a coupled inductor. The coupled inductor has a primary winding and a secondary winding, a first end of the primary winding is coupled to the first half bridge stage at a first node, a second end of the primary winding is coupled to the load, a first end of the secondary winding is coupled to the load, a second end of the secondary winding is coupled to the second half bridge stage at a second node. An inductor circuit is coupled between the first and second half bridge stages and a first end of a load circuit.
